X-ray tomography system, automation, and remote access at beamline 2-BM of the Advanced Photon Source

Synchrotron X-ray diffraction study of load partitioning during elastic deformation of bovine dentin

“…The sample was then taken to sector 2-BM-B of the APS where it was thawed, and mounted in a PBS filled plastic tube. The tomography was done using the standard configuration of station 2-BM [48,49], at an Xray energy of 26 keV, with 0.125°rotation increment between projections and with magnification lens of 2.5Â and 1.25Â (producing respectively). The lower resolution scan covered the entire specimen cross-section, while small sections of the cementum were out of the field of view in the higher magnification scan.…”

Regridding reconstruction algorithm for real-time tomographic imaging

“…At third-generation synchrotron facilities, highly brilliant X-rays coupled with modern detector technology permit routine acquisition of high-resolution tomograms in a few minutes, making high-throughput experiments a reality (Hintermü ller et al, 2010;Marone et al, 2010;De Carlo et al, 2006;Rivers et al, 2010;Chilingaryan et al, 2010). Recently, the latest detectors based on CMOS technology (Baker, 2010) have been tremendously pushing the achievable temporal resolution bringing real-time tomography closer.…”

3D morphological evolution of porous titanium by x-ray micro- and nano-tomography

“…This method can be further applied to fabricate nanoporous b-Ti-Cr-Zr alloy with Ti, which is mechanically superior to pure a-Ti. 15 When immersing a Cu-Ti alloy with small Zr and Cr additions, Cu 80 (Ti 0.847 Cr 0.098 Zr 0.056 ) 20 , into a Mg melt at 810°C, Mg selectively alloys with Cu, while the remaining Ti-Cr-Zr phase separates into a solid skeleton with sub-micron strut size. Therefore, an Mg-Cu/Ti-Cr-Zr composite was formed as a bi-continuous structure.…”
